METAL WINDOW.

Application led October 29. 1927. Serial lj'o. 287,967.

This invention relates to windows and more particularly to metal windows.

One of the objects of this invention 1s provide a metal window construct1on,.1n which a weatherstrip adapted to seal the side opening between the sash and the )amb may be applied in a simple and effective manner.

Another object is to provide such a construction, in which the sash will be resiliently held against rattling.

Another object is to provide a construction in which such weatherstripping may be applied in such a manner as to be easily re newable.

Another object is to provide a simple construction, which will be economical to manufacture and easy to install. p

Further objects will appear fromthe following description, taken in connectlon wlth the accompanying drawing, 1n which-.-

Figure 1 is a detail, in vertical section, of a window embodying this invention; and

Figure 2 is a horizontal section on line 2 2 of Figure 1.

Referring to the drawing, 1 designates a window j amb, which may be constructed of sheet metal or other suitable material, in box section, as shown in Figure 2, so as to provide a housing for the sash weights Mounted on the inner face of the jamb 1 1s an auxiliary jamb 3. This auxiliary Jamb is preferably constructed with an outstanding central portion connected by angular flanges 4 to side flanges 5, which in turn terminate in lateral flanges 6 engaging the 1nner face of the jamb l and secured thereto by means of screws 7 or other suitable fastenings. Mounted on the jamb 1 are outside and inside plates 8 and 9, respectively, secured to the jamb 1, by means of screws 10, rivets 11, or other suitable fastenings. The plates 8 and 9 provide outer and inner guiding flanges 12 and 13, respectively, ada ted to guide the upper and lower sash 14 an 15.

Mounted on the auxiliary jamb 3, by means of rivets 16 or other suitable fastenings, is a parting stile 17. The stile 17 may be constructed o sheet metal bent back upon itself so as to form guiding flanges 18 adapted to engage the guide flanges 19 of the sash 14 and 15 to guide the latter in their up and down movement. After the bends forming the flan es 18, the metal is bent back to provide anges 20. The flanges 20 are spaced from the walls of the auxlliary jamb 3 so as to permit the insertion therebetween of the flange 21 of a. strip 22 of resilient material, preferably sheet metal.

The strip 22 is bent outwardly from the flange 21 and turned back at its extremity, as shown in Figure 2, so that its curved edge presses yieldingly against the side face of the guide flange, 19. This strip not only provides a weather seal to prevent drafts from passing around the flange 19 from the outside to the inside of the window, but also presses the sash yieldingly against the guide flange of the jamb so as to rigidly support the window atall times and prevent its rattling. The pressure is yielding so that it does not interfere with the movement of the windows for opening and closing.

The strip 22 may be applied to the parting stile by inserting the flange 21 between the flange 20 and the auxiliary j amb, the insertion being made from the end of the j amb. Suitable stops 24, secured to the auxiliary jamb or the vflange 20, may be placed at proper points therealong so as to prevent the insertion of the strip 22 too far and in order to properly position the same. The strip 22 thus inserted is interlocked with the parting stile so as to be permanently held in assembled relation thereto and in a position to properly engage the flange 19 of the sash. ,l

It will be seen, therefore, that this invention provides a window construction which is not only cheap to manufacture, but which is very effective in service. The auxiliary jamb 3 has spaced bearing points against the jamb 1 at the flanges 6. This jamb may be adjusted relatively to the sash by means of the bolt 25, of which there may be any number. With the auxiliary jamb adjusted to give the proper clearance between the guide flanges, the strip 22 keeps the sash under a yielding tension so as to prevent rattling and at the same time provides an effective weatherseal. This strip is placed in a location where it is protected from the weather and where it is not subject to contact by anyone handling the window. Once in place, therefore, it will be undisturbed throughout its life. In case of wearing out of this strip, it is easily replaced by dismounting the auxiliary jamb and simply inserting a new strip. The cost of repairs is thus reduced to a minimum. The arting stile itself is also easily removab e in case of excessive wear.

It is obvious that various changes may be made, within the scope of the appended claims, in the details of construction without departing from the s irit of this invention; it is, therefore, to e understood that this invention is not limited to the specific details shown and described.

Having thus described the inventlon, what is claimed is:

1. In a metal Window having a sash, a jamb and a parting stile therealong, a loose strip of resilient material interlocked with the stile and pressing yieldingly against the sash.

2. In a metal window having a sash, a jamb and a parting stile therealong, a continuous strip of resilient material extending along the stile and pressing yleldingly against the sash.

3. In a metal window having a sash, a jamb and a arting stile therealong, a loose strip of resi ient material extending along and interlocked with the stile and pressing yieldingly against the sash.

4. In a metal window having a sash provided with a guide flange and a parting stile engaging said ange, a continuous strip of resilient material extending along the stile and pressing yieldingly against the side face of said iange.

5. In a metal window having a jamb and a sash, an auxiliary jamb, a parting stile on said auxiliary jamb, and a resilient stri confined between said auxiliar jamb and said stile and bearing against t e sash. 6. In a metal window having a jamb and a sash having a guide fiange, an auxiliary jamb, a parting stile on said auxiliary j amb and a resilient stri confined between said auxiliary jamb andp said stile and bearing against the side face of the guide flange.

7. In a metal window having a sash, an auxiliary jamb, a parting stile mounted thereon and having a flange spaced therefrom, and a strip of resilient material insertable between said fiange and said jamb so as to bear against the sash.

8. In a metal window having a sash, :in auxiliary jamb, a parting stile mounted thereon and having a flange spaced therefrom, a stri of resilient material insertable between said fiange and said jamb so as to bear against the sash, and a stop adapted to locate said strip.

9. In a metal window having a sash, an auxiliary jamb, a parting stile formed of sheet metal bent back upon itself to provide a guiding flange for the sash and having a flange spaced from said jamb, and a strip of resilient material interlocked with said flange and bearing a ainst the sash.

10. In a metal Window having a sash, an auxiliary jamb, a parting stile formed of sheet metal bent back upon itself to provide a guiding flange for the sash and having a flange spaced from said jamb, and a stri of resilient material confined between sai latter flan e and said jamb and bearing against the sas.

In testimony whereof I affix my signature this 15th day of October, 1927.
